What does Zechariah 14:16 mean?

It will happen in that day, that a great panic from Yahweh will be among them; and they will lay hold everyone on the hand of his neighbor, and his hand will rise up against the hand of his neighbor.

Judah also will fight at Jerusalem; and the wealth of all the surrounding nations will be gathered together: gold, and silver, and clothing, in great abundance.

So will be the plague of the horse, of the mule, of the camel, and of the donkey, and of all the animals that will be in those camps, as that plague.

It will be, that whoever of all the families of the earth doesn’t go up to Jerusalem to worship the King, Yahweh of Armies, on them there will be no rain.

If the family of Egypt doesn’t go up, and doesn’t come, neither will it rain on them. This will be the plague with which Yahweh will strike the nations that don’t go up to keep the feast of tents.

This will be the punishment of Egypt, and the punishment of all the nations that don’t go up to keep the feast of tents.
